The pattern behind the list
Look at the last digit of each answer. From 25 × 1 to 25 × 10 it goes like this, and then the same pattern repeats every ten facts all the way up to 25 × 15:
- 5
- 0
- 5
- 0
- 5
- 0
- 5
- 0
- 5
- 0
Working out big facts
You do not need to learn all 15 facts by heart. Use the method for the 25 times table instead: Split 25 into 20 and 5: work out the 20s and the 5s, then add them.
Split 25 into 20 and 5. 20 × 15 = 300 and 5 × 15 = 75, so 25 × 15 = 300 + 75 = 375.
25 × 15 = 300 + 75 = 375
